The 50/30/20 Rule: How to Budget Your Money (With Euro Examples)

The 50/30/20 rule is one of the simplest ways to budget your money: half of your take-home pay goes to needs, 30% to wants and 20% to savings. No spreadsheet with 40 categories, no tracking every coffee. Just three buckets and one decision each payday.

The rule is simple, but making it work with real rent, real prices and a real salary in Germany or elsewhere in Europe takes a few adjustments. This guide shows you how to calculate your own 50/30/20 budget, what belongs in each bucket, worked examples in euros, and what to do when the numbers don’t fit.

What Is the 50/30/20 Rule?

The 50/30/20 rule (sometimes written as the 50/20/30 rule or the 50-30-20 budget) splits your net income, the money that actually lands in your account, into three parts:

The method was popularised by Elizabeth Warren and her daughter Amelia Warren Tyagi in their 2005 book All Your Worth: The Ultimate Lifetime Money Plan. Its strength is that it gives you a target for each area of your life without forcing you to micro-manage every purchase.

How to Calculate Your 50/30/20 Budget

1. Find your monthly net income. Use your payslip (Gehaltsabrechnung), not your gross salary. In Germany, tax, health insurance, pension and unemployment contributions are already deducted, so the net figure is what you budget with. Not sure how big the gap is? See gross vs net salary in Germany.
2. Multiply by 0.5 to get your needs limit.
3. Multiply by 0.3 to get your wants limit.
4. Multiply by 0.2 to get your savings target.
5. Compare with what you actually spend. Look at your last one to three months of bank statements and sort each payment into a bucket. If you have never done this, start with how to track your expenses.
6. Adjust and automate. Move your savings share on payday with a standing order (Dauerauftrag) so it happens before you can spend it.

50/30/20 Budget Examples in Euros

Here is how the split looks at three different take-home salaries:

Example: a €2,800 net salary

Lena earns €2,800 a month after deductions. Her needs bucket of €1,400 could look like this:

• Warm rent (Warmmiete, including heating): €950
• Electricity and internet: €90
• Groceries: €260
• Deutschlandticket: €58
• Mobile phone and liability insurance: €42

That leaves €840 for wants and €560 for savings, for example €200 into her emergency fund, €260 into an ETF savings plan and €100 into a holiday sinking fund. Her figures are illustrative, but the structure works at any income.

What Counts as Needs, Wants and Savings?

The hardest part of the rule is being honest about which bucket an expense belongs to. A simple test: would you still have to pay this if you lost your job tomorrow? If yes, it is probably a need.

Needs (50%)

• Rent or mortgage, plus service charges (Nebenkosten)
• Electricity, heating, water, internet
• Basic groceries and household items
• Transport to work (public transport ticket, or car costs if you truly need one)
• Insurance you must have, such as personal liability (Haftpflicht)
• Childcare
• Minimum payments on loans and credit cards

Wants (30%)

• Restaurants, takeaway and coffee out
• Streaming services and subscriptions
• Travel and weekend trips
• Clothes beyond the basics, gadgets and hobbies
• Gym memberships and upgrades (a nicer flat or car than you need)

Savings and debt repayment (20%)

• An emergency fund of three to six months of essential costs
• Investing, for example a monthly ETF savings plan (ETF-Sparplan)
• Retirement saving beyond your state pension (see how to start saving for retirement)
• Sinking funds for irregular costs such as car repairs, gifts or annual insurance
• Extra debt repayments above the minimum

Grey areas are normal. A basic phone contract is a need, the newest smartphone is a want. Supermarket groceries are a need, delivery apps are a want. Decide once, write it down and stay consistent.

Is the 50/30/20 Rule Realistic?

For many people, yes, as a starting point. But in cities such as Munich, Frankfurt, Paris or Amsterdam, rent alone can take 40% or more of a single salary, which makes keeping needs at 50% difficult. That doesn’t mean the rule has failed. It means you need a version that fits your situation.

The rule is a guide, not a test you pass or fail. What matters most is that you save something every month and that you know where your money goes. If your needs are high, the first place to look is usually the wants bucket, not your savings.

50/30/20 Alternatives and Variations

If you want more detail than three buckets, a zero-based budget, where every euro gets a job, is the next step. You can build one with our guide on how to create a sustainable budget.

How to Make the 50/30/20 Rule Work in Real Life

• Use separate accounts. Many German banks let you open free sub-accounts (Unterkonten or “Spaces”). One for needs, one for wants, one for savings makes the rule visible.
• Pay yourself first. Schedule your 20% transfer for the day your salary arrives.
• Give your wants a weekly limit. €840 a month becomes roughly €190 a week, which is much easier to keep track of.
• Review once a month. Ten minutes is enough to check whether each bucket stayed on target.
• Raise savings when your income rises. Put at least half of every pay rise into the savings bucket to avoid lifestyle inflation.

Common 50/30/20 Mistakes

• Using gross salary instead of net income
• Counting wants as needs (“I need this subscription”)
• Forgetting annual and irregular costs, which then blow up a single month
• Saving only what is left at the end of the month instead of saving first
• Giving up after one bad month instead of adjusting the percentages

Frequently Asked Questions

Is it the 50/30/20 rule or the 50/20/30 rule?

They are the same idea. Whichever order you see (50/30/20, 50/20/30 or 30/20/50), it means 50% for needs, 30% for wants and 20% for savings and debt repayment.

Is the 50/30/20 rule based on gross or net income?

Net income: your take-home pay after taxes and social contributions. If you are self-employed, use your income after setting aside money for tax and insurance.

Do debt payments count as needs or savings?

Minimum required payments are needs. Anything you pay on top to clear debt faster counts towards the 20%. If you are deciding where extra money should go, read pay off debt or save money first.

What if my rent is more than 50% of my income?

Use a 60/30/10 or 70/20/10 split for now, cut wants where you can, and look for ways to raise your income or lower your housing costs over time. Then move back towards 50/30/20 step by step.

Does the 50/30/20 rule work on a low income?

It can be hard when most of your money goes on essentials. Start by saving any amount, even €20 a month, and focus on building a small cushion first. Our guide to managing money on a low income has practical steps.
